This evaluation board for the FDA903D 1 x 45 W class D digital input automotive power amplifier, with load current monitoring and wide voltage operation range, is highly suitable for typical automotive audio, infotainment and telematic applications in conjunction with suitable automotive microcontrollers. The amplifier can also be interfaced with the SPC582B Chorus automotive microcontroller and can also provide Electric Vehicle Warning Sounds (or Acoustic Vehicle Alerting Systems, AVAS) solutions. The FDA903D amplifier comes in a PowerSSO-36 slug-down package and features a configurable power limiting function, high-speed I²C and legacy mode interfaces, and an internal finite state machine. The initial state of the device is the standby state from which it will not be possible to exit until the I2C interface has been correctly enabled: this means providing correct supply voltage, the I2S clock, the I2S data and a valid combination of enable pins in order to determine the I2C device address. This system is required by new vehicles to alert pedestrians of the presence of electric powered vehicles that are generating much less noise. Warning sounds may be driver triggered (like a horn) or automatic mimicking engine sounds. From 2021 according to government regulations, the vehicle must make a continuous noise level of at least 56 dBA (within 2 meters) if the car is going 20 km/h (12 mph) or slower, and a maximum of 75 dBA. Each combination of the Enable pins represents an address. Up to eight devices can be used in the same application with a single I2C bus. The internal I2C registers are pre-set in "default condition", waiting for the I2C next instruction. The return in Standby condition, (i.e. all enable pins at 0), will result in a reset for the amplifier. As defined in the finite state machine, the same event will happen if PLL is not locked, I2S is missing or not correct, Vcc is removed for system reset. FDA903D works only in I2C slave mode. The combination of AEK-AUD-D903V1 with AEK-MCU-C1MLIT1 hosting SPC582B Chorus automotive microcontroller offers a viable low-cost solution for entry-level AVAS systems.

The AEK-COM-GNSST31 evaluation board is based on the certified Teseo-LIV3F global navigation satellite system (GNSS) module with embedded TeseoIII single die standalone positioning receiver IC. The tiny, affordable, and easy-to use module guarantees superior accuracy and reduced time to first fix (TTFF) thanks to the on-board 26 MHz temperature compensated crystal oscillator (TCXO) and dedicated 32 KHz real-time clock (RTC) oscillator. The evaluation package is used in conjunction with the X-CUBE-GNSS1 firmware to provide the necessary acquisition, tracking, navigation and data output functionality without external memory support. The AEK-COM-GNSST31 evaluation board can be readily connected with an SPC5 MCU for automotive application development as part of the AutoDevKit™ initiative.

The AEK-COM-ISOSPI1 is a SPI to isolated SPI dongle, which allows converting SPI signals in isolated SPI signals, thereby reducing the number of necessary wires from 4 to 2. The ISOSPI protocol features differential communication to ensure higher noise immunity and robustness for long distance communications. As the ISOSPI signals can travel for several meters, this protocol is particularly suitable for automotive high voltage applications where electrical isolation is required by the safety standards and the cable length can affect the communication among devices located in distant parts of the vehicle. The AEK-COM-ISOSPI1 is based on the L9963T general purpose SPI to isolated SPI bi-directional transceiver, which can transfer communication data incoming from a classical 4-wire based SPI interface to a 2-wire isolated interface (and vice versa). The L9963T hosted on the AEK-COM-ISOSPI1 can be configured either as a slave or as a master of the SPI bus and supports any protocol of 8-to-64-bit SPI frames. The SPI peripheral can work up to 10 MHz when configured as a slave. The SPI clock frequency can be programmed (250 kHz, 1 MHz, 4 MHz, or 8 MHz) when the device is configured as a master. The transceiver is natively compatible with the L9963E isolated SPI, allowing its usage in battery management system (BMS) applications. The basic BMS analog front-end node board is the AEK-POW-BMS63EN. From the microcontroller side, the AEK-COM-ISOSPI1 board can be connected via SPI with SPC5, Stellar and STM32 microcontroller families. In the AutoDevKit ecosystem software package, we created two example demos: SPC582B - ISOSPI1_LEDdriver test application for discovery, to be downloaded on an AEK-MCU-C1MLIT1 MCU board, and SPC58EC - ISOSPI1_LEDdriver test application for discovery, to be downloaded on an AEK-MCU-C4MLIT1 MCU board. The MCU board of both demos communicate with an AEK-LED-21DISM1 LED driver board using two AEK-COM-ISOSPI1 dongles. The aim of these demos is to show how to configure the AEK-COM-ISOSPI1 to allow the MCU board to communicate with the LED driver board via SPI protocol. After uploading the demos, the MCU boards can send a command to the LED driver board via SPI protocol through the first AEK-COM-ISOSPI1, which converts the SPI signal into an ISOSPI message and then transmits it to the second AEK-COM-ISOSPI1, which converts it back into a SPI message. Finally, the message is transmitted to the AEK-LED-21DISM1 LED driver that executes the command sent. The commands sent are related to the activation of the bucks and the reading of the status register of the AEK-LED-21DISM1 LED driver.

The AEK-CON-C1D9031 is a connector board dedicated to bridge AEK-AUD-D903V1 board hosting FDA903D automotive digital class D power amplifier and AEK-MCU-C1MLIT1 board hosting a SPC582B Chorus family automotive MCU with 1MB flash. On the board there are two main female strip connectors: a 19x2 one is used for AEK-MCU-C1MLIT1 while the 20x2 is used for the AEK-AUD-D903V1. An additional 15x2 male strip J2 is used to connect the AEK-MCU-C1MLIT1 and AEK-AUD-D903V1. It is mandatory to fill the connector with all jumpers, except for the position 19-20 (I2S Test). A regulator and a level translator are employed to adjust level of a debug signal coming from the audio amp for current monitoring during play. This signal is called I2S test and it is digital and synchronized with the audio data sent through the I2S interface. To make the system a potential audio sub-module, a CAN transceiver has been added employing L9616. This allows to sent audio commands to the MCU through CAN interface. A 6-pin male connector is available on the board for this purpose. The last 4-pin plug of the board is dedicated to connect a separate board with two potentiometers actuated with sliders. The values of the potentiometers are fed to the MCU ADCs (analog-to-digital converters) compatible with 5V levels. One potentiometer could be employed to control the volume while the second one is used to accelerate the sound played. Traditionally, the audio sub-module is used for typical automotive infotainment applications. Recently, the Electric Vehicle Warning Sounds (AVAS) system has become a new growing application for automotive audio. This system is required by new vehicles to alert pedestrians of the presence of electric powered vehicles that are generating much less noise. Warning sounds may be driver triggered (like a horn) or automatic mimicking engine sounds. The speed slider can be employed to modify the played sound to simulate a change of the engine rpm. From 2021 according to government regulations, the vehicle must make a continuous noise level of at least 56 dBA (within 2 meters) if the car is going 20 km/h (12 mph) or slower, and a maximum of 75 dBA. The combination of AEK-AUD-D903V1 with AEK-MCU-C1MLIT1 through AEK-CON-C1D9031 offers a viable low-cost solution for entry-level AVAS systems. The CAN interface allows remote control of several audio sub-modules that can be placed around the vehicle.
